This invention relates to valves fot'the' for use `in'tlush tanks and the like. .i l

`'Brieiiy stated, :an important object ofthis Y invention isto provide a float operatedvvalve construction in' which vthe valve is at the pressure side of: the valve seat so that the the water is effectively employed to holdthe valveztirmly seated'and thereby repair.

,A further aiin is to provide a float oper-'f-v ated valve which is quiet in use, positive in operation against substantial water pressures,v and one in which the parts may readily be replacedin A further object is to provide'a valveiof he character vspeciiied which is of highly' simplified construction,"durable in use 'and whichmay be installed vwithout a'substantial departure from established practices.

Other objects and advantages will be apparent during the course of the following description. I

In the accompanying Vdrawing forming a application in which like numerals are. employed to designateV Vlike parts throughoutthe,same, v f f Y Figure 1 is a perspective oftheimproved valve installed;v f

The member 6 extends throughthe bottom of a tank 7 and is Afirmly vheld in'place by fastening means 8. i Suitable gaskets 9 may be employed to `establish a water tight connection between the member 6 and the bottom of the tank.

`The upper'horizontal branch of theU- shaped inlet `member 5 has an eXteriorly threaded depending terminal portion tol which a valvecage or casing 10 is threaded andan outlet casing 11 is in turn threaded to the lower portion of the casing 10.

In carrying out the invention, the intermediate kportion of the valve casing 10V is provided with a seat for engagement on its lly l adapted the necessity of `frequent la highlyVv convenient and' a vertical sectional view j Ufshaped` water inlet f with a combined water upper side 'by avalve'la` o'lihardrubber or other material lfound su'itable-ior. the'y purpose.
